Front

How does friction affect motion?

Back

Friction opposes the motion of objects, causing them to slow down or stop.

Front

What happens to a person's body in a car when the car suddenly stops?

Back

The person continues to move forward due to inertia.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
